Arctic Pak Hose Replacement Set
16.1 General Information
In ambient temperatures below 65°F (18°C), use of Arctic Pak heated
chemical hoses is often required for consistent, quality results. The
Arctic Pak will keep the chemicals at an even, warm temperature to
allow uniform processing.
This product is primarily intended to keep already warmed materials at
temperature during transit to the dispensing INSTAFLO™ Gun. Chemi-
cal tanks should be stored in a warm location until use, and may require
use of a tank heater band set (please see Section 15).
The Arctic Pak is used in place of unheated chemical transport lines
where described throughout this manual (Sections 3.3 and elsewhere).
DO NOT use standard 30 foot FROTHPAK hoses in an Arctic Pak
heated jacket.
DO NOT use Arctic Pak hoses in place of nitrogen lines or for
conveying non-polyurethane chemicals of any type.
DO NOT use the Arctic Pak with any flammable materials.
Standard unheated chemical lines are 30 feet in length, but are often
connected in series to produce longer lengths as job needs require.
Locate unneeded hose (if any) out of the traffic path to prevent a trip
hazard. Never attempt to cut the Arctic Pak to a shorted length or to
splice in additional hose.
The Arctic Pak is fully pressure checked and is flushed with
nitrogen at the factory prior to shipment. To keep the hoses from having
moisture or other undesirable materials introduced into them, please
keep the hose end plugs in place
until beginning installation.
16.2 Preparing and Installing the Arctic Pak
1. Unpack and examine your Arctic Pak for possible
shipping damage. Do not use if damage has occurred.
2. As per Section 3.3, connect your Gun/Hose Assembly
to the in-line on-off valves.
3. Remove plugs from the dispenser end of the hose.
The dispenser end is the end without the electrical
cord entering it. Connect the in-line on-off valves to
the dispenser end of the Arctic Pak hoses and tighten
securely. Close the on-off valves if not already closed.
4. The electrical cord servicing the heaters enters at the
tank end of the jacket. Remove plugs from the tank
end of the hose.
5. Connect the tank end of each hose to the appropriate
chemical tank on-off valve. The hose with the red
colored sleeve and blue body should connect to the
isocyanate tank. The blue sleeved, black bodied hose
should connect to the polyol tank. Close the on-off
valves if not already closed.
6. Follow the remaining operating manual instructions
for Chemical Hose Installation (Section 3.3). Also
execute the instructions regarding System Pressuriza-
tion (Section 4.1), and System Purging and Testing
(Section 4.3) as they are the same for both heated and
